DEPTH RANGING WITH MOIRE PATTERNS
First Claim
Patent Images
1. A method for three-dimensional mapping of an object, comprising:
- projecting with a projector a set of fringes on the object;
capturing an image of the object in a camera;
processing the captured image so as to detect a Moiré
pattern associated with the object and so as to extract depth information from the Moiré
pattern; and
configuring the projector and the camera so that a locally unambiguous characteristic of the Moiré
pattern is related to a depth of the object.

Abstract
A method for three-dimensional mapping of an object, including projecting with a projector a set of fringes on the object and capturing an image of the object in a camera. The method further includes processing the captured image so as to detect a Moiré pattern associated with the object and so as to extract depth information from the Moiré pattern, and configuring the projector and the camera so that a locally unambiguous characteristic of the Moiré pattern is related to a depth of the object.

20. Apparatus for three-dimensional mapping of an object, comprising:
-
a projector which is configured to project a single set of fringes on the object; a camera which is configured to capture an image of the object; and a processor which is configured to process the captured image so as to detect a Moiré
pattern associated with the object and so as to extract depth information from the Moiré
pattern,wherein the projector and the camera are configured so that a locally unambiguous characteristic of the Moiré
pattern is related to a depth of the object. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. Apparatus for three-dimensional mapping of an object, comprising:
-
a projector which is configured to project a first set of fringes and a second set of fringes on the object; a camera which is configured to capture an image of the object; and a processor which is configured to process the captured image so as to detect a Moiré
pattern associated with the object and so as to extract depth information from the Moiré
pattern,wherein the projector and the camera are configured so that a locally unambiguous characteristic of the Moiré
pattern is related to a depth of the object. - View Dependent Claims (32, 33, 34, 35, 36, 37)
